China will install a total of 141,624 new desktop computers
running Linux in school classrooms this year. The PCs are
ticketed for the Jiangsu Provincial Department of Education, for
an educational program called the School-to-School Project. They
will run Sun Wah Linux's Debian-based RAYS LX.

The San Diego Unified School District has selected Novell's SLED
10 (SUSE Linux Enterprise Desktop) as the standard platform for
its "Always-On Learning Initiative," a mobile computing
initiative intended to help students achieve academic success and
prepare them for life and work in the 21st century.

This school district turning to the Linux desktop and open source
is not a small matter. The San Diego Unified School District is
the second-largest school district in California, serving more
than 130,000 students, 100,000 of whom are in grades three
through 12.

Brazil's Ministry of Education ("MEC") is installing Linux in
labs used by 52 million schoolchildren, reports KDE developer
Mauricio Piacentini. Piacentini's blog post describes MEC's
"Linux Educacional 2.0" as "a very clean Debian-based
distribution, with KDE 3.5, KDE-Edu, KDE-Games, and some tools
developed by the project."

Piacentini says that typical labs use one server and seven
satellite PCs, each of which supports two KVM (keyboard, video,
and mouse) stations. Thus, most labs have 15 available
workstations. For labs in rural locations with limited
electricity, a single server can support up to seven KVMs.
There's also a set-up with a large TV monitor for special needs
children. Some 29,000 labs will be completed this year, with
53,000 labs set up by the end of next year.

Let's do the math:

53,000 x 15 = 795,000 Linux desktops. At $50 US per license,
that alone is $39,750,000 simple cost avoidance over Microsoft
Windows licenses. Imagine that, a $40 million US savings in
Brasil Education Labs only, not including other savings in other
locations as well.
